However, there are subtle differences between Free SW and Open Source SW in terms of history, philosophies pursued, and so on.

Olis (Open Source License Information System) is a site that aims to improve convenience for Open Source SW developers, expand the range of Open Source SW application, and contribute to development of relevant industry by providing a Korean version of domestic and foreign up-to-date information related to more professional license observances for Open Source SW being used (written/distributed) after being downloaded easily on the web.
